The Hidden Life Within Perception, Thought, and Will

Let us take the other case, in which we not merely perceive, but we think. When we think, it is not a sense perception. Sense perceptions may give rise to thought, but true thought does not consist of sense perceptions, it is a more interior process. When we think, we make no impression in our physical body with the actual thought, but we do upon our etheric body. When we think, all that is in the thought does not enter into us. Were all that is contained in thought to enter into us, we should feel, every time we think, nothing but living, elemental beings pulsing in us; we should feel inwardly alive. I mentioned once at Munich that if a person were to experience thoughts just as they are, he would feel somewhat as if he were in an ant heap. Thoughts would live in him, everything would be alive. We do not perceive this life in our human thought, because again, only what is like the froth of it enters our consciousness and forms those shadow-pictures of thought which appear in us as our thinking. On the other hand, that which permeates thought as living force, sinks into our etheric body. We do not perceive the living beings, the living elemental beings swarming through us, but only an extract, something like a shadow of them; but the other part, the life, does enter into us and as it enters into us pervades us in such a manner that again a battle takes place, this time in our etheric body, between the progressing spirits and Ahriman, the Ahrimanic beings. And what is the outcome of this battle? It is that thoughts do not appear in us as they would do if they were alive. Were they to appear as they actually are, we should feel ourselves within the life of the thought-beings moving hither and thither; but we do not perceive this, and our etheric body, which otherwise would be transparent, is rendered opaque. I might say that it becomes somewhat like a smoke-topaz, which has darker layers in it, while quartz is quite transparent and pure. In the same way our etheric body is filled with a spiritual obscurity and that which thus fills our etheric body is the treasure of our thought.
